Abstract:

Objective

To investigate the effect of ertapenem in preventing surgical site infection (SSI) of rectal cancer (RC) surgery.

Methods

From March 2010 to March 2022, a total of 775 RC patients who received perioperative prophylaxis with antibiotics to prevent SSI in Fujian Medical University Union Hospital were collected. After propensity score matching, 230 RC patients were enrolled in the ertapenem group (46 cases) and the non-ertapenem group (184 cases). The efficacy of prevention of SSI in the ertapenem and non-ertapenem groups was compared using following propensity score matching (PSM). Risk factors of SSI in RC surgery were analyzed by univariate and multivariate Logistic regression anlaysis.

Results

The incidence of SSI in the ertapenem group was significantly lower than that in the non-ertapenem group (8.7% vs. 22.3%, P=0.038). Univariate analysis found ertapenem (OR=4.317, P=0.038), operation method (P=0.0001) distance from the anal verge to the tumor (OR=0.718, P=0.011) and operation time (OR=1.010, P=0.002) were closely related to SSI. Multivariate analysis revealed that non-ertapenem (OR=4.392, 95%CI: 1.325~14.564; P=0.016), abdominoperineal resection (APR) surgery (OR=25.65; 95%CI: 2.960~222.37; P=0.003) and operation time (OR=1.011, 95%CI: 0.003~1.019; P=0.004) were independent risk factors of SSI.

Conclusion

Ertapenem can effectively prevent SSI in rectal cancer surgery. RC patients with APR surgery and long operation time are candidates that should receive ertapenem for the prevention of SSI.
